Let’s get you a data plan that works!

#1 Pick

GigSky

Overall, I recommend GigSky to travelers in Europe because it’s the most reliable eSIM I’ve used. It’s fast, works across multiple countries without a problem, and you don’t need data to top up, which is a game-changer when you’re already wandering around.

The unlimited plans mean you don’t have to stress over every GB, and since GigSky runs on its own network instead of piggybacking off others, the connection is stronger and more reliable.

What’s the Best eSIM for Europe?

If you just want the answer without a lot of tech jargon, basically, GigSky is the best eSIM for Europe. It’s the one I trust most for fast, reliable data when I’m bouncing around from one country to the next.

Here’s why: most eSIM companies are just resellers. They buy access from local carriers and pass it on to you.

That which sounds fine until the network randomly drops, and the eSIM provider has zero ability to fix it.

GigSky is different. It operates as a Heavy MVNO, meaning it partners directly with over 400 networks worldwide to run its own data infrastructure.

That gives it way more control over coverage and speed… so your service doesn’t randomly die mid-train ride through the Alps.

If one network goes down, GigSky can move you to another one, automatically. That means your connection is going to be way more reliable.

It also lets you use one eSIM across multiple countries, which is a big deal if you’re traveling all over Europe and don’t want to re-download a new eSIM every time you cross a border.

I’ve used it in Italy and Ireland, and it worked like a dream. I even used my eSIM instead of wifi (one summer, my apartment in Sardinia didn’t have wifi at ALL so I relied on eSIMs the entire time).

Take a peek at this table I made to compare GigSky and other options:

Provider	Speed & Reliability	Unlimited Data?	Throttling Policy (Fair Usage)	Best For
GigSky	⭐️⭐️⭐️⭐️⭐️ Operates own global network	✅ Yes	⚠️ Throttled after 2.5GB/day — speeds reset every 24 hrs	Remote workers, multi-country travel
Holafly	⭐️⭐️⭐️ Resells local networks	✅ Yes	⚠️ FUP: Speeds may drop after “high usage,” no official GB limit disclosed	Casual travelers, social media use
Airalo	⭐️⭐️ Budget, variable coverage	🚫 No	⚠️ Speeds drop to 1 Mbps after 3GB/day	Light browsing, short trips

⚠️ Heads up: Most “unlimited” eSIMs have some kind of Fair Usage Policy. GigSky is one of the few that actually discloses the throttle point (2.5 GB/day), while others keep it vague. Either way, if you’re bingeing Netflix or using your phone as a hotspot 24/7, you will notice a slowdown at some point.

📉 Most “unlimited” plans throttle you without warning. GigSky tells you upfront—and still resets speeds daily. Get the plan with no surprises! 👈

Why GigSky Is My Go-To eSIM in Europe

Speed and Reliability

Let’s be real, nothing is more frustrating than having no signal when you’re traveling and you’re desperately trying to find where your guided tour starts in a city you barely know.

I can totally relate to rushing somewhere and feeling totally lost, and without Google Maps to help me out, I’m definitely going to get lost.

That’s why I always make sure to get an eSIM with GigSky. Most eSIM companies just resell access from local networks.

GigSky does things differently. They work directly with over 400 providers worldwide and manage their own service. That means better speed, more stable connections, and fewer of those “why isn’t my phone working?” moments where you’re frustrated and lost while on vacation.

I’ve used GigSky all over Europe, including Italy, Spain, and Ireland, and it’s held up for everything: hotspotting, remote work, Zoom calls, and Google Maps.

Especially when I didn’t have wifi in my apartment in Sardinia one summer, I used my iPad’s data plan with GigSky as a hotspot for my laptop to connect to the internet. Total lifesaver!

Unlimited Plans That Actually Work

One of the things I love most about GigSky is their unlimited data plans.

I don’t know about you, but I hate traveling and constantly having to think about how much data I’m using or having to conserve my data, i.e., “Don’t watch that video, it’ll eat all your data!”

Going with an unlimited plan takes the stress off the table.

Now, here’s the “catch.” Like pretty much every single provider I’ve researched out there, GigSky does have a Fair Usage Policy.

After about 2.5 GB of high-speed data per day, your speed will slow down for the rest of the day… but it resets every 24 hours.

So let’s say you use a lot of data and by 5 pm, you hit that 2.5 GB, you’ll be back to normal by the next day. Even at slower speeds, you can still check email, send messages, or make wifi calls.

I actually didn’t know this and I found out the hard way. I streamed half of a movie on Netflix and a ton of YouTube videos, and then, suddenly my internet got much slower. That’s when I found out about the limit.

The difference with GigSky is that they’re upfront about the limit. Other companies, like Holafly, tuck this info behind vague “Fair Usage” language without ever telling you the actual number. Which I don’t love.

At least with GigSky, you know what you’re working with, and they’re upfront about that. That’s the kind of company I like purchasing from.

😮 Most “unlimited” eSIMs companies hide the fine print, but GigSky is upfront about when speeds slow down and resets daily so you can keep scrolling, streaming, and hotspotting without the guesswork. ➡️ Try a GigSky unlimited plan

GigSky’s Free eSIM Trial

For anyone new to eSIMs, this is a big deal. So many providers expect you to dive in headfirst with a paid plan.

GigSky’s free option is basically a risk-free trial, and honestly, I wish I’d had this when I was first figuring eSIMs out. You don’t need to enter a credit card or commit to a purchase just to see if it works for your phone.

You get 100 MB of data with the free plan. That’s not a ton, but it’s plenty for testing things out, like setting up the eSIM, checking if your device is compatible, and making sure you can connect before your trip kicks off.

If you’ve never used an eSIM before, this kind of trial is super helpful. It takes the stress out of trying something new and lets you test-drive it.

How I’ve Actually Been Using It

As I mentioned earlier, for the summer I lived in Sardinia, I somehow managed to survive without wifi in my apartment. I work 100% remotely. This was a big deal.

I lived with a roommate, and she didn’t want to pay for wifi, because she’s rarely at home and works at the beach as a stand-up paddle board instructor.

Luckily, I thought of a good solution.

I bought an unlimited data plan with GigSky for my phone and used it as a hotspot to connect my laptop to the internet. It kept me online for work calls, file uploads, and the usual doomscrolling (haha). Honestly, it was way less stressful than running around to cafés or coworking spaces every day.

I’ve also recently used GigSky in Ireland, and it was just as reliable.

I recently got a new iPhone, I found out the hard way that my SIM is locked for 60 days.

It was pretty bad timing, because I got the new phone the same week I was traveling to Ireland for TBEX.

But instead of panicking, I topped up my GigSky eSIM on my old phone and used it as a hotspot for the new one. Crisis averted!

That’s what I like about GigSky. It’s something I actually use every day, whether I’m working abroad or just trying to travel around a new city without losing service.

📶 I ran my entire apartment’s internet off this eSIM—Zoom calls, uploads, and streaming included. If you’re working remotely in Europe, this is your lifeline.

Pro Tips for Using an eSIM in Europe

A little prep makes eSIM life so much easier. Here are a few tips I’ve learned the hard way:

Keep a backup option – If you’re upgrading phones or dealing with SIM locks, hang onto your old device or use an iPad/tablet. You can always run your eSIM there and use it as a dedicated hotspot.

Check compatibility first – Not all phones support eSIMs, and some carriers lock new devices for 60 days (i.e. Verizon). Double-check before you travel.

Install before you go – Download your eSIM while you’re still on wifi at home. That way, you’ll land ready to go instead of trying to figure it out in baggage claim.

Know about throttling – “Unlimited” data plans usually comes with fine print. With GigSky, speeds slow down after 2.5 GB/day but reset every 24 hours. Plan around it if you’re going to be streaming a lot.

Hotspot smartly – Using your phone as a hotspot is a lifesaver, but remember it eats data faster. If you need it for work, factor that into your plan choice.

Cons of Using GigSky

No eSIM is perfect, and GigSky isn’t either. Here are a few things to keep in mind before you commit:

Daily data cap – Unlimited isn’t truly unlimited. After about 2.5 GB/day, speeds slow down until the next day. The good news is the reset happens every 24 hours, and the slowed-down speeds are still fine for maps, messages, and email.
Not the cheapest option – GigSky usually costs a little more than budget eSIMs like Airalo. But that extra cost buys you a smoother, more reliable connection — something I’d rather have than deal with random dropouts.
Hotspot use can drain data – Using your phone as a hotspot works well, but it does eat through your allowance faster. With the right plan, though, it’s still a dependable way to get work done remotely (I literally ran my whole Italy apartment on it).
Phone compatibility – Not every phone supports eSIMs yet, and some carriers lock new devices for 60 days. If you run into that, an easy workaround is to activate GigSky on an older phone and use it as a hotspot — a trick that saved me in Ireland.

These aren’t dealbreakers — just things worth knowing before you go. For me, the reliability far outweighs the drawbacks, which is why GigSky is still my go-to in Europe.

Who is GigSky best for?

GigSky works for a lot of different travelers, but it shines most for a few specific groups:

Remote workers and digital nomads – If you need reliable data for Zoom calls, file uploads, or running a hotspot from your phone, GigSky is one of the few eSIMs that won’t let you down.
Multi-country travelers – Crossing borders every few days? GigSky saves you from downloading a new eSIM each time. One plan, one app, and you’re covered across Europe.
First-time eSIM users – The setup is simple, the app is easy to manage, and the free 100 MB plan gives you an easy way to test it out.
Travelers who value reliability over bargain hunting – GigSky isn’t always the cheapest option, but it’s the most reliable. If you’d rather pay a little extra and know your internet won’t cut out in the middle of your high-speed train ride, this is the eSIM for you.

If that sounds like you, GigSky is going to feel like a game-changer.

Wait a Sec, What’s GigSky One?

GigSky One Plan pricing page featuring eSIM for Europe: 50 GB options—1 month at $53.99, 3 months at $136.59, and 12 months at $518.30—with more savings on longer terms clearly highlighted.

If you travel a lot or are a digital nomad who’s always in a new country, GigSky has a subscription option called GigSky One that’s literally perfect for you.

Instead of buying separate eSIMs for each trip, you sign up once and get data that works across tons of countries under a single plan. Finally!

The cool part is you can pay monthly, quarterly, or yearly, so if you are planning on nomading for 3 months (but not a full year), it’s extremely convenient.

I like that it’s flexible. You can cancel whenever you want, use your phone as a hotspot, and not have to worry about downloading a new eSIM every time you cross a border.

If you’re bouncing around Europe (or just always on the move), GigSky One is a good idea. I haven’t really seen anything else like this on the market, at all.

🗺️ One plan, endless borders. GigSky One covers multiple countries with zero eSIM swaps. Ideal for digital nomads on the move.
